STOVE Filed Aug. 24, 1931 EF. 3. v (47 Patented May 7, 1935 STOVE Bertrand n. kahn, Cincinnati, omo, assignor to The Estate Stove Company, Hamilton, Ohio, a

corporation of Ohio Application August 24, 1931, Serial No. 5511;047 '7 Claims. (01. 158-115) This invention relates to stoves.

One of the principal objects of the invention is the provision of a stove having a member of simple construction which serves as a support for the cooking surface, and also extends beneath the cooking surface as an interceptor, having channels for directing fuel flow from the burners to a pilot light for ignition therefrom.

Another object of the invention is the provision of an interceptor plate which is integrally formed from sheet metal and is grooved for re-. ceptionof a cover piece which cooperates with the grooves to provide fuel flow passages for flash! back ignition of the stove burners from a pilot light.

Other objects and advantages of the invention will be apparent from the following description,

the accompanying drawing, and the appended .claims.

In. the drawing, which discloses a preferred embodiment of the invention,

Fig. 1 is a plan view of a stove constructed in accordance withthe present invention; certain of the parts being broken away for clearness in illustration; 1

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1;

Fig. 3 is a vertical sectional view taken on the line 3-3 of Fig. 1, and

Fig. 4 is a fragmentary vertical sectional view taken on the line 4--4 of Fig.1.

The drawing, in which like characters of reference designate like parts throughout the several views thereof, illustrates a stove of the kitchen range type having a top member H) which as shown is integrally formed of sheet metal. The member ID comprises a rim portion l l which is in the shape of a rectangular frame having a flat top portion l2. At the inner edge of the rim II a depression I3 is formed which serves as a seat v for the support of a cooking surface l4 shown as a grille composed of spaced bars. I A flange portion 15 continues downwardly and inwardly from the depression l3 and terminates at a plate portion l6 which forms a closure for the area defined by the rim ll. The plate portionv l6 extends across the entire area within the flanges I3 of the rim sides and, except for openings II in which the stove burners [8 stand, the plate provides a closure which serves as an effective interceptor for the burner heat.- The relative proportioning of the parts of the member I0 is such that sufficient vertical height is provided between the depression l3, upon which the grille I4 is carried, and the surface of the plate portion ll, so that the burners l8 may be mounted at substantially the level of the plate l6 and will stand properly spaced from the grille upon which the cooking vessels rest.

The plate portion I 6 of the top member I0 is constructed to provide for flash-back ignition of the burners l 8 from a pilot light 20 which, like the burners I8, is supported in some suitable manner from the stove structure. Ignition of the burners I 8 from the pilot 20 is accomplished by provision of channels in the plate portion l6 which serve to direct a flow of fuel from each burner to the pilot light so that upon ignition of this fuel at the pilot the flash of the burning fuel then carries back through the channel for ignition of fuel issuing from the burner jets. -As shown, a depressed central portion 22 is formed at substantially the mid-point of the plate portion, and from this portion 22 depressed grooves 23 extend which terminate adjacent the burners l8 at the burner openings I! of the plate. The depressed portions of the plate are formed therein during the fabrication of the member ID and thus serve as simple means of providing channels whereby fuel may be conducted from the burners to the pilot.

A cover member 24 provided for the depressed portions of the plate and cooperates with the grooves to form fuel flow passages. As shown, the plate 24 is a simple spider shaped casting having a central portion25 which overlies the depressed portion 22, and outwardly extending arms 26 which overlie the grooves 23. The cover arms 26 have spaced downwardly extending ribs 21 which lie between the side walls of the grooves 23 and thus serve to form a substantially closed passage as well as provide a locating means for properly positioning the cover member over the grooves.

As shown, the pilot light 20 stands beneath the plate portion "5 and is positioned concentrically with respect to an opening 30 in the depressed portion 22 and an opening 3| in the cover 24 which stands vertically related to the opening 30.

While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is. to be understood that the invention a depression therein at the inner edge for support of a cooking surface, a downwardly and inwardly extending flange projecting from the rim depression, and a plate portion extending from the flange and forming a closure for the rim portion, said plate portion having burner'openings therein and fuel conducting channels extending between the pilot and the burners, said channels being formed as depressions in the plate portion, and a readily removable cover member overlying said channels and cooperating therewith to form fuel conducting passages for flash-back ignition of the burners.

2. In a stove, a plurality of burners, a pilot light, a plate extending between said burners, said plate having a depressed fuel conducting groove formed therein between the pilot light and a burner for flash-back ignition of the said burner and a readily removable cover overlying the groove and cooperating therewith to form a fuel conducting passage.

3. In a stove, a plurality of burners, a pilot light, an interceptor plate extending between said burners, said plate having depressed grooves formed therein extending between the pilot and the burners, and a readily removable cover member overlying said grooves and cooperating therewith to form fuel conducting passages for flashback ignition of the burners.

4. In a stove, a plurality of burners, a pilot light, an interceptor plate extending across the burner space and having burner openings therein, said plate having depressed grooves formed therein extending between the pilot and the burners, and a cover member removably received in said grooves and cooperating therewith to form fuel conducting passages for flash-back ignition of the burners.

'aooaeae 5. In a stove, a plurality of burners, a pilot light, an interceptor plate extending between said burners, said plate having a depressed central portion and depressed outwardly extending grooves formed therein, said grooves terminating adjacent the burners, and a fiat cover member receivable on the plate portion for cooperation with the depressed part of the plate to form fuel conducting passages for flash-back ignition of the burners, said cover member having downwardly, extending ribs engageable with the groove walls.

6. In a stove, a plurality of burners, a pilot light, an interceptor plate extending between said burners, said plate having depressed grooves formed therein extending between the pilot and the burners, and a cover member for said grooves comprising channels of inverted trough shape receivable in the grooves and held therein only by gravity to form fuel conducting passages for fiash back ignition of the burners. V

7. In a stove, a plurality of burners, a pilot light, an interceptor plate extending between said burners, said plate having a central depressed portion with a pilot light opening formed therein and grooves extending from the central portion to the burners, a cover for said central portion and grooves receivable on said plate for cooperation with the grooves to form fuel conducting passages for fiash-back ignition of the burners, said cover having an opening therein concentrically related to the pilotlight opening of the
